Sakeem is a landscape architect. When he creates a lawn, his supplier charges $0.43 per square foot for sod. Sakeem charges his customers $2.00 per square foot to lay the sod. The profit Sakeem makes when creating a lawn varies directly as the number of square feet of sod he lays. Create an equation to show Sakeem’s profit when laying sod, where y is the profit and x is the number of square feet of sod. Recall that profit is the difference of the amount earned and the amount spent.

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
